Specification of Letters Patent.

Patented Dec. as, 1919.

Application filed May 23, 1919. Serial No. 299,268.

To all whom it may concern:

Be it known that 1, JOHN LOGAN CAMP- BELL, a cltizen of the United States, res1ding at El Paso, in the county of El Paso and State of Texas, have invented new and useful Improvement in Foundations and Housing for Railway or Other Signal Apparatus, of which the following is a specification.

My invention relates to improvement in foundation and housing for signal appa- 'atus in which a single structure having bottom, side and top walls forming a subterranean vault serves as a foundation for signal apparatus imposed thereon, houses signal apparatus placed therein, affords passage way for direct inside electric wire or pneumatic pipe extending from. the signal apparatus in. the vault to the signal apparatus on the vault and in which no part of the vault serves exclusively as a founda tion or a housing but in which the vault as a unit, and in every part; without structural division or distinction of parts serves equally and fully as a foundation and as a housing for signal apparatus.

1 attain these objects by the structure illustrated in the accompanying drawing, in which-- Figure 1 is an elevation showing the vault a,'supporting the hollow signal mechanism case b, the hollow signal mast c and the signal semaphore d. v

Fig. is a section through the vault on the line m% of Fig. 3'

Fig. 3 is a top plan view of the vault of rectangular plan. The plan may be rectangular, polygonal, circular or oval.

Similar letters refer to similar parts in,

all of the figures.

In the figures, 0. shows the walls (bottom, side and top) of the vault inclosing. the vault space 0. The letter 0 indicates the inclosed vault space in which signal apparatus (not shown) such as battery cells, compressed. air retainers, electric wire or pneumatic pipe, etc., are housed in the vault.

The letter 72. indicates an aperture in the top wall of the vault through which electric wire or pneumatic pipe connections may extend from the signal apparatus in the vault to the signal apparatus mounted upon the vault. This aperture may be of any required size and location under and within the limits of the bottom area of the hollow signal mechanism case b.

The letter shows a man-hole in the top wall giving access to the vault.

The letter 9 shows an aperture in the side wall for conductors, not material to this invention.

The letter 2' indicates the ground surface line.

I am aware that, prior to my invention, a foundation to carry and a vault to house signal apparatus built as two separate structures, one part of which is designed for and serves exclusively as a foundation carrying parts of the signal apparatus and the other part of which is designed for and serves exclusively as a receptacle housing other parts of the signal apparatus have been used.

What I claim as new and desire to secure by Letters Patent of the United States is 1. A structure having bottom, side and top walls made in one piece forming a subterranean laterally closed vault which serves as a foundation supporting signal apparatus and as a receptacle housing signal apparatus in which no part serves exclusively as such foundation or as suoh housing but in which the vault as a unit, and in every part, and without structural division or distinction of parts, serves equally and fully every requirement of a foundation and housing for signal apparatus together with a signal pole and 1ts appurtenant equipment mounted on such structure and secured thereon substantially as and for the purpose described.

2. In combination with a subterranean laterally closed vault for the reception and housing of signal apparatus, said vault havbottom, side and top walls made in one piece, an aperture in the top wall of said vault and a hollow signal mechanism case and a hollow signal mast separate from said vault, mounted on said top wall over said aperture whereby electric wires or pneumatic pipe for operating the signal mast mechanism may be extended directly from the interior of said vault into the interior of said hollow mechanism case and the said hollow mast, substantially as and for the purpose set forth.

3. In combination with a subterranean laterally closed vault for the reception and housing of signal apparatus, said vault having a top wall with a horizontal plane upper surface, an aperture in said top wall, a hollow signal mechanism case and a hollow signal mast securely mounted on said top Wall and disclosed over said aperture Whereby electric Wire or pneumatic pipe for con trolling the signal mast mechanism may be extended directly from the interior of said vault into the interior of the said hollow mechanism case and the said hollow mast, substantially as and for the purpose set forth.

4. In combination With a subterranean vault in the form of a hollow box-like struc ture having its'bottom, side and top walls formed in one piece, the top Wall of said vault havinga substantially horizontal upper surface, a manhole in said top wall adjacent one side thereof to permit access to the interior of said vault, a comparatively small aperture through said top Wall, a signal pole structure mounted upon said vault, said signal pole structure eomprisin a hollow signal mechanism case and a'hol ow signal mast extending upward from said hollow signal mechanism case, said signal mechanism case being disposed over said aperture and provided with bolting flanges resting on said top Wall, together with bolts extending through said top wall and through said bolting flanges, whereby said signal 'pole structure is securely retained upon said vault, substantially as and for the purpose set forth.
